[Maximiliano Sandoval]

Fixes the cargo doc lint:

```
warning: unclosed HTML tag `uuid`
  --> pbs-datastore/src/datastore.rs:60:41
   |
60 | ///  - could not stat /dev/disk/by-uuid/<uuid>
   |                                         ^^^^^^
   |
   = note: `#[warn(rustdoc::invalid_html_tags)]` on by default

warning: unclosed HTML tag `uuid`
  --> pbs-datastore/src/datastore.rs:61:26
   |
61 | ///  - /dev/disk/by-uuid/<uuid> is not a block device
```
